Above, the new face of British currency, announced by the Royal Mint. The striking new designs, selected from an open competition that attracted four thousand entries, are the work of a 26-year old graphic designer named Matthew Dent. They are Mr. Dent’s first foray into currency design.

Below, the new five dollar bill, introduced last month by the United States Department of the Treasury. The new design, which features a big purple Helvetica five, is the work of a 147-year-old government agency called the United States Bureau of Engraving and Printing. It employs 2,500 people, and has an annual budget of $525,000,000. —JH
